I don’t recall Charles’s drawing code exactly, but I think this is just part of the solution. It’ll always be correct for the part of the view being drawn, but there’s no guarantee that the whole view will be redrawn if the relationship between the bounds origin and the circle changes. I think Charles still needs something to force redrawing of the whole view when the view geometry changes.
Of course, if the view geometry never changes, or the relationship of the circle to the bounds origin never changes, then I think the forced redrawing isn’t necessary.
